That number is the maximum pressure the tire can hold, not the recommended pressure for the vehicle. For the most accurate reading (not to mention the most consistent one), make sure the car has been sitting overnight or at least has been parked for a few hours.ĭo not inflate your tires to the pressure listed on the tire itself. The reason you check tire pressure when they’re cold is that as tires roll along the road, friction between them and the road generates heat, increasing both the temperature and the air pressure. Most passenger cars will recommend 32 psi to 35 psi in the tires when they’re cold.
If there’s no sticker on the door, you can usually find the specs in the owner’s manual. On newer cars, the recommended tire pressure is most commonly listed on a sticker inside the driver’s door. That’s the one you should follow when filling them up with air to the recommended pressure, measured in pounds per square inch, or psi. Your car has a recommended tire pressure that will give the best gas mileage, handling and tire life for that car - and it’s written right on the vehicle’s door. Having the correct tire pressure is extremely important for getting good gas mileage and the most life out of your tires. Related: Should I Use Nitrogen Instead of Regular Air in My Tires?
